摘要： A voltage detecting apparatus with a capacitor having a switch for detecting a voltage of a direct-current power source, which can detect a malfunction of the switch without additional parts and effects to a measurement time in a normal condition, is provided. When a microcomputer measures a voltage between both terminals of a capacitor plural times, the sampled voltages are at most a prescribed threshold value, and a voltage decreases at least a prescribed difference of voltages in sampling order (each of all measured voltages between both terminals decreases at least a potential deference from a voltage measured previously in sampling order). Furthermore, when the voltage between both terminals of the capacitor becomes 0 volt in condition that a fifth switch SW5 is opened, it is judged that the fifth switch is in an abnormal condition.

摘要： An alternating signal from a signal generator is applied to a direct current source via a detecting resistor and a coupling capacitor. A detecting member detects a voltage amplitude change appeared at a contact between the detecting resistor and the coupling capacitor. Based on the voltage amplitude change, a correction member corrects a first measuring voltage when a capacitor is connected to a contact between an anode of the direct current source and a ground, and a second measuring voltage when the capacitor is connected to a contact between a cathode of the direct current source and the ground. Based on the corrected first and second measuring values and a voltage across the direct current source when the capacitor is connected to the anode and the cathode of the direct current source by a voltage measuring member, a calculation member calculates a resistance between the direct current source and the ground.

摘要： A DC power supply, a DC motor driven by DC voltage outputted from the DC power supply, and a control unit outputting a drive control signal to drive the DC motor are provided. A motor drive switch is provided between the DC power supply and the DC motor, and a brake switch is connected to a positive input terminal of the DC motor. The motor drive switch is on while receiving the drive control signal and outputs an output current monitor signal while current is being applied to the motor drive switch. The brake switch is configured to operate faster than the motor drive switch and is off while at least one of the drive control signal and the output current monitor signal is on. Accordingly, when the drive control signal is supplied, the brake switch is turned off, and then the motor drive switch is turned on. When the supply of the drive control signal is stopped, it is not until the motor drive switch is turned off, the current applied to the motor drive switch is stopped, and then the supply of the output current monitor signal is stopped that the brake switch is turned on.

摘要： Disclosed is a method of manufacturing a double-sided wiring substrate wherein wiring patterns having a low resistivity are formed on both surfaces of a substrate. A fine pin hole is formed in a thin insulating film having excellent durability by a pin or laser beams. A thin metal film is formed on the upper and lower surfaces of the insulating film and the inner wall of the fine pin hole by vacuum deposition. A thick metal film is formed on the entire thin metal film by electroplating. Thereafter, portions of the thin and the thick metal films formed on the upper and lower surfaces of the insulating film are etched while leaving a portion of them on the inner wall of the fine pin hole. Conductive patterns each having a layered structure of the thin and the thick metal films are thus formed on the upper and lower surfaces of the substrate. The "roll-to-roll system" that is, every step of manufacturing is performed by unrolling and feeding the insulating film rolled up around the roll, can also be applied. This enables to make the productivity extremely efficient.
